Rough turning is an inexact science: turning wood too thick will lead to splits, and turning wood too thin will lead to distortion that cannot be removed because not enough thickness is left. Once dry, it is mounted on the lathe a second time and turned to its final form. Rough turning is typically used on most functional work and some art pieces.

A worker sprays a urethane finish onto a timber. Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs. [1] [2]
Hard turning is a type of turning done on materials with a Rockwell C hardness greater than 45. It is typically performed after the workpiece is heat treated. [3] The process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding.
Segmented turning, also known as polychromatic turning, is a form of woodturning on a lathe where the initial workpiece is composed of multiple parts glued together. The process involves gluing several pieces of wood to create patterns and visual effects in turned projects.
For spindle turning, the wood is held on the lathe either by both ends (between the headstock and tailstock) or by one end only using a lathe chuck [2]. Wood is generally removed by running a turning tool down the slope of the wood from a larger diameter in the wood to a smaller diameter.
Skilled fine woodworking, however, remains a craft pursued by many. There remains demand for hand crafted work such as furniture and arts, however with rate and cost of production, the cost for consumers is much higher. Modern woodcarving usually refers to works of wood art produced by woodcarvers in the form of contemporary art. This type of ...
A #7 finish is produced by polishing with a 280–320 grit belt or wheel and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they will be very dull. Carbon steel and iron are commonly polished to a #7 finish before chrome plating.
